Have you ever wondered: is my mental state actually good or bad today? Not by picking an emoji -- but by using your sleep duration, heart rate variability (HRV), resting heart rate, and step count, calculated by an algorithm, to give you a real answer. Vitalync is a biometric-based mental state tracking tool. It connects to Apple Health, reads your body data, and through a proprietary Adaptive Integrity Engine algorithm, generates two core metrics every day: - Mental Clarity -- how sharp your cognitive state is - Physical Energy -- how well your body has recovered Not a questionnaire. Not a guess. Data. -- Core Features -- Adaptive Algorithm Engine - Four detection modes: Full Spectrum (Sleep+HRV+HR) > Awakening > Drive > Manual - Interaction effect detection: when sleep deficit + HRV anomaly occur together, the system detects compounded fatigue - Dynamic baseline: compared against YOUR history, not generic standards - Fully transparent algorithm: see exactly where every point comes from 3 AI Advisor System Not one AI, but three with completely different styles: - Core Analyst -- CBT cognitive behavioral framework, rationally deconstructs your thinking patterns - Cyber Monk -- mindfulness guidance, helps you find space in the present moment - Punk Coach -- straight talk, no fluff, action only Each advisor can see your 30-day data trends (ROOT membership) and give evidence-based suggestions. State K-Line Chart Review your mental state trends like a stock K-line chart. 7-day, 30-day, and annual trends at a glance. Each data point can be expanded to view that day's detailed analysis. Focus Timer and Meditation 7 built-in focus modes (deep work/reading/fitness/meditation...), every minute of timing converts to experience points and currency rewards. -- Cyberpunk Identity System -- This is not just a health tool -- it is your cyber alter ego. - Multiple theme skins: from default matrix green to various classic color schemes, each unlocking with your level - Levels and XP: daily logging, focus sessions, and meditation all accumulate XP, continuously unlocking new content - Streak tracking: watching your consecutive days grow is its own positive feedback loop - Compute coins: in-app universal currency for AI conversation credits or character unlocks -- Privacy Commitment -- - All health data is stored only on your device - No tracking, no ads, no data sales - AI analysis sends only anonymized statistical summaries, never raw biometric values - You can delete all your data at any time -- ROOT Membership -- The free version includes complete state tracking, logging, and basic AI analysis. ROOT membership unlocks: - 30-day deep data review + behavioral attribution analysis - Up to 100 AI conversations per day - All 3 AI advisors - Conversation memory (cross-session continuity) - Long-cycle trend charts (30-day/annual) Subscription options: - Monthly: $2.99/month - Annual: $19.99/year (save 44%) - Lifetime: $49.99 one-time purchase Payment will be charged to your Apple ID account.

Kine is a body-state dashboard for Apple Watch users. It reads heart rate, HRV, sleep, activity, energy expenditure, and other HealthKit data. Combined with live Apple Watch heart rate, Kine turns scattered signals into clear, actionable views of performance, recovery, body load, and training rhythm. With Kine, you can observe: • Current performance and body-load state • Sleep, HRV, resting heart rate, and activity trends • Live heart-rate feedback during workouts • Front-camera PPG pressure reference scans for personal trend observation • Nap detection and recovery prompts • High-load and overload signal reminders • 24-hour body-dynamics challenges with friends Kine is designed to organize health data into understandable state and trend signals. HealthKit data is processed on your device. The challenge feature uses CloudKit only for a randomized device ID, challenge status, and aggregated performance summaries.

If you experience chest pain, difficulty breathing, fainting, persistent palpitations, or other serious symptoms, seek professional medical help immediately.
